Abstract: ABSTRACT OF THE DISCLOSURE A counting and grouping apparatus for receiving articles such as fruit, marchalling the articles so as to fill up a number of parallel supply lines for presenting a number of the articles in line abreast in the leading positions in the supply lines, the number in the line abreast being equal to (or a fraction or multiple of) the number of articles to be counted into a group and a moving belt conveyor bearing at intervals along its length lines of fingers in line abreast across the belt, which fingers align with the leading position of the supply lines and shift the line of articles in said leading positions on to the conveyor belt as the fingers pass the exit ends of the supply lines. Gates are described for blocking one or more of the supply lines to control the number. The fingers have an upright operating position for picking off the articles and a non-operating position folded down on to the belt.  The number in the final group can thus be varied by adjusting the number of fingers in each line which are in an operating position. Each group is collated from line abreast into a serial sequence for presentation to subsequent handling equipment.

Abstract: Abstract of the Disclosure A sound-attenuating inlet duct is provided for a gas turbine engine wherein the inlet duct includes a casing defining, in serial flow relationship, a minimum area throat of predetermined axial extent, a diffuser and a cylindrical section. Sound-absorbent acoustic material is disposed upon the inner walls of the duct in the cylindrical section. A first amount of acoustic attenuation is provided by accelerating the motive fluid to high subsonic velocities through the throat. A second amount of acoustic attenuation is provided by locally accelerating the motive fluid in the vicinity of the acoustic material, thereby imparting a velocity component to the acoustic waves which is normal to the acoustic material, thereby enhancing absorption. By sizing the various sections of the inlet duct in a unique predetermined relationship the effects of the two sources of acoustic attenuation may be made additive.

Abstract: IMPROVED METHOD AND APPARATUS FOR PRODUCING           STEEL BOX TOES TO BE USED IN SAFETY SHOES     ABSTRACT OF THE DISCLOSURE     A flat strip of metal, preferably coiled upon itself, is fed into a draw press and subjected to pressure to produce a generally bowl-shaped workpiece having irregular outer edges within which is defined a pair of mirror-imaged toe cap parts. The toe cap parts occur in angularly opposed relation to one another and are surrounded by irregular edge portions.  The toe cap parts are separated and gauged by a press operation in which parting is combined with a trimming operation in a unique manner. An improved tool construction for processing the workpiece in-cludes mating die bodies which are progressively moved toward one another in contact with the workpiece.  During a first move-ment inner sides of the toe cap parts are located in a centered position on one of the mating die parts.  Completion of the die motion trims away irregular outer edges of each toe cap part and simultaneously die cut edges of the toe cap parts are con-formed to a desired shape.

Abstract: INTEGRATED HIGH CAPACITY COMPRESSOR                 ABSTRACT OF THE DISCLOSURE A compressor motor has a flywheel connected directly to a motor shaft which drives two opposed pistons that are simultaneously compressed so that the bearing loads are balanced. A double inlet blower is connected to said shaft and has one inlet for drawing cooling air through a crankcase for cooling the connecting rod bearings. A second inlet draws air through a vent formed in a shroud member. The blower discharges the air from both inlets into the shroud member which then directs the air to the cylinder sleeves and heads for cooling purposes. The cylinder, piston skirts and piston rings are self-lubricated by containing a fluorocarbon thereby substantially reducing the heat generating friction between said members.

Abstract: ABSTRACT OF THE DISCLOSURE         A screw-type clamping collar includes a flexible band having first and second end portions and inner and outer surfaces with a rack of teeth formed in said first end portion and having a part thereof protruding inwardly of the inner surface of the flexible band, on the side of the parts to be clamped.  The second end portion of the band has a screw bearing saddle housing rigidly connected to it, and an axial opening formed therein having a width corresponding substantially to the width of the protrusions. These protrusions are engaged and maintained transversely in the opening of the band over a length corresponding approximately to the length of the housing and of the screw to guide movement of the band beneath the screw.  The mounting arrangement of the saddle housing on the band resists transverse movement when the clamping collar is subject to substantial stresses, thus aiding in preventing disassembly of the saddle and band when the collar is in use.

Abstract: ABSTRACT OF THE DISCLOSURE         A control system for use in combination with a bushing assembly of the type wherein glass fibers are drawn through an orifice plate having a flat undersurface against which bulk gas is directed to effect cooling and fiber attentuation.  The system controls operation in the event of fiber "break out", by lowering the temperature of the bushing assembly, increasing the rate of flow of bulk gas against the orifice plate, controlling the drawing action of the collet used to draw fibers from the plate, and spraying cooling water against the fibers being drawn from the plate.  Control is effected through means of a common main control unit and manual controls are provided to permit operation of the control system to selectively control the operating mode of the system and increase the bulk flow of gas for orifice plate clearing purposes.

Abstract: ABSTRACT OF THE DISCLOSURE              Aqueous solutions of 9 technetium salts wherein the 99technetium is in reduced valence state, when administered to mammals, permit identification of the skeleton and of calcareous tumors by scintigraphy (radiographic scanning).  The solutions are conveniently prepared by mixing one or more phosphonic acids (or their salts) with one or more reducing salts, and adding the mixture to an aqueous solution of a pharmaceutically acceptable 99pertechnetate salt.  Reduction of the valence of the technetium occurs rapidly, and the resulting solution is adequately stable for use in scintigraphy.            The phosphonic acid and reducing salt components can be premixed.  Aqueous solutions of the premix are stable for long periods of time in the absence of free oxygen and the premix is stable to air so long as it is dry.
